Chart.js library not working on device


#1

Hi,

I have a problem using Chart.js for my project hopefully you can help me:

I am loading the library in my index.html:

<script src="libraries/Chart.min.js"></script>

Then in my Controller I set up my chart like this:

var summary= new Chart(ctx).Doughnut(data, {});

In the browser everything loads fine, but on my Android device I get an Reference error saying that Chart is not defined in the logcat output. I have no clue where to start debugging this. I also tried other paths for the library and loading it directly from the web but with the same result.

I even tried to copy the content of Chart.min.js into my controller without any success.

Any ideas what I am doing wrong?

Thanks in advance!

You have to load this script before ionic.

Could you show us your index.html?

I figured it out. Your tip that it wasn’t in the right order made me have a look at my index.html again. I am using the Yeoman generator for Ionic and my project therefore uses Bower. I think there was an Issue with that. Initially I included the Library right below cordova.js. Now I included it right below

<!-- build:js scripts/scripts.js -->

Here is my complete index.html for reference:

<!DOCTYPE html>

  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
